' MECHANISM FOR DELIVERING GLASS.

Specification of Letters Patent.

Patented Sept. 2, 1919.

Application fll'ed November 12, 1915. Serial No. 61,015.

To all whom it may concern:

Be it known that I, RAPHAEL NE'ITER, a

citizen of the Republic of France, residing in the city and county of New York, State of New York, have invented new and useful Improvements in Mechanisms for Delivering Glass, of which the following is a specification, reference being bad tothe accompanying drawings, in which- Figure 1 is an elevation partly in section, of apparatus embodying my invention; Fig. 2 1s a plan showing the mold table and glass-delivering mechanism; Fig. 3 is a section on lines IIIIII of Fig. 1; Fig. 4 is a section on lines IV-IV of Fig. 1, and Fig. 5. is a detail of the cutting mechanism. My invention relates to mechanisms for delivering glass from the furnace mouth to a mold carrier, and consists in mechanism cooperating with the furnace mouth and the mold carrier, arranged so as to permit the mold carrier to be operated continuously, and at the same time provide each mold with a batch of glass as it passes beneath the place of delivery. My invention also consists of the construction and cooperation of the parts which I shall hereinafter describe and claim.

Referring to the drawings, A indicates the usual delivery spout of a furnace or tank, B an auxiliary spout, G the cut-oiLmechanism and D- themold carrier or mold table. Beneath the usual openin 2 in the spout A, above which is positioned the usual stopper 3, is a support 4:, depending from the spout A, which has'an annular chamber 5, with a central bottom aperture 6, intended for the reception of the head 7of the auxiliary spout B, which seats in and rotates in such space. Y

The mold carrier or mold table D is arranged'beneath the spout A and rotates about a fixed shaft 8, whichhas mounted on its upper end a spout-supporting member 9. A socket 10 is provided in the upper end of the shaft 8 fora projection 11 on the member 9, so that the member 9 may rotate upon the shaft 8. The. member 10 has a bifurcated upper end 12, between the arms of which the upper end of the spout B is secured. and supportedby means of trunnions 13; The spout B may also be adjusted by means of the set screw 14, which is mounted in themember 9 and bears upon the under side of the spout B.

The spout .B is preferably comprised of refractory lining 15 and a supporting cas- 1ng 16, and is arranged so that its upper or intake portion lies prefeiably above the axis of the mold table, while its discharging portion lies directly over the molds, so that its center of motion lies in the axis of the mold table, and the path of movement of the discharging portion is concentric with the path of movement of the molds. Attached to the lower end of the spout B is a .water-cooled plate 17, to which the cutoff mechanism C is attached. I have shown the cut-off mechanism G in the form of counterpart members 18 of'clam-shell sha e, which operate horizontally to cut off iilie glass as the members come together. When the shells 18 come together, they cut ofi and sup ort the lass and permit the spout to e swun tion above one mo d to dischargingposition rom discharging posiabove the succeeding mold. The counterpart shells 18 are normallyheld in closed position by the spring 19, which is mounted on the pivots 20 of the shells 18, and engages pins 21 on therear' extensions 22 and 22,

of the members and thus forces together their cuttin edges as is best shown in Fig. 3. The 'auxi iary spout B and the cutting mechanism 0 are operated by a series of spout moving members 23, which are mount-1 ed on the table and each of which is desi ed to operate in conjunction with the a jacent mold and to'engage the rear extension 22 on one of the counterpart shell members 18 and rotate it to open position against the tension of the spring. The

other counterpart member is likewise operatedthrouglh the mutilated gears 24.. Each member 23 as a downward extension 25,

carrying a projection 26, which is intended to engage a cam surface27 on a stationary 'thetable from the cam sur ace 27, consists in a spring 29 colled around the member 23,

and bearing at its lower end upon the table and at its upper end against a collar on the member.

Mounted on the shaft A-is a spring 30, one end of which engages the downward extension 31 of the spout supportmg member 9, so arranged as to return the spout, when it has been released from contact with one of the movable members 23, to its initial position beyond which it cannot be swung because of a stop 32, secured to the shaft 8, which lies in the path of a depending web 33 on the under side of the auxiliary spout B.

The mechanism for driving the table consists in the gear wheel 34:, which is actuated by a worm 35 on the shaft 36, which is driven from any suitable source of power.

The operation of my device is as follows:

When the device is set in operation, glass flows through the opening 2 in the spout A into the large, upper end of the auxiliary spout B, and down through the auxiliary spout B to its lower or discharging end. The glass may be maintained inmolten condition in the spout B by means of blasts of gas or other suitable heating medium, which may be introduced'into and along the spout where desired. As the table D is set in rotation the spout B is held by the tension of the spring against the projection 32, and as a mold comes underneath the spout B the movable member 23 adjacent the mold will strike the rear extension 22 on one of the counterpart cutting shells 18 and will open the shells, permittlng the glassto flow into the mold. The member 23, by its bearing against the extension 22, will carry the spout B along with the table in alinement with the mold, as is shown in the dotted line position in Fig. 2, until it has almost reached the full-line position shown in Fig. 2, at which point the projection on the lower end of the member 23 will strike the cam surface 27 and draw down the upper end of the member 23 outof contact with the extension 22, and thus permit the counterpart shell members 18 to come together and cut ofl the flow of glass, as is shown in Fig. 1 As soon as the member 23has been depressed out of contact with the extension 22, the spring-29 on the shaft 8 will swing the spout B back to its initial position'against the stop projection 32, in which position it momentarily rests until the next mold comes into alinement with it, and the mechanism is again set in operation by the engagement of the. succeeding movable member 23 with the rear extension 22 of the cut-ofi' mechanism.

It will be seen that the glass continues to run into the mold during the forward movement of the spout B and until the extension 22 becomes disengaged from the movable member 23, and that during its return move ment, the glass will continue to flow into the spout, so that an adequate supply of molten glass will have collected and will be ready to be deposited into the succeeding mold when the succeeding movable member 23 engages and opens the shells of the cut-off C and advances the spout B.

The terms and expressions which I have employed are used as terms of description and not of limitation, and I haveno intention, in the use of such terms and expres-v sions, of excluding any mechanical equivalents of the features shown and described, or portions thereof, but recognize that various structural modifications are possible within the scope of the invention claimed.

What I claim is:

1. In mechanisms for delivering glass, a spout in the furnace, a continuously movable mold table arrangedunder said spout,

a plurality of molds mounted thereon, ,and a glass transferring member having its receiving portion arranged in the axis of the mold table and its delivery portion vertical alinement with each mold successively, said glass transferring member being mounted for movement about the axis of the mold table andbeing adapted for reception of the glass as it flows fromthe spout and for delivering glass successively into the successive molds.

'2. In mechanisms for delivering glass, a continuously movable mold table, a plurality of molds mounted thereon, a'spont in a furnace, a glass transferring member positioned above the mold table and having its receiv- 1n portion arranged in the axis of the mold ta 1e and of the spout and having also its delivery portion arranged to move about said axis in a path of movement coincident with a'portion of the path of movement of the molds, said member being adapted to receive glass from the spout and deliver it to said mold successively and being also mounted for rotation about the axis of the table, and means for moving said receptacle about said axis in the same direction as the table while in discharging position and for moving it in i the opposite direction while in non-discharging position. p

3. In mechanisms for-delivering glass, a continuously moving mold carrier, a plurality of molds .mounted thereon, a furnace spout mounted above said mold carrier, a glass transferring mechanism having its receiving portion mounted for movement in the vertical axis of the mold carrier and spout and having its delivery portion adapt- 1 rier so as to come into register vvith the next. succeeding mold. 4. In mechanisms for delivering glass a spout in a furnace having a flow opening on its under side, a recess in said spout beneath said flow opening, a glass transferring member having its receiving portion mounted for rotation in said recess, a continuously movable mold table. having its axis in vertical alinement with said flow opening, molds 10 on the mold table, a discharge opening from said member arranged to register successively with said molds and means for moving said member with said mold through the arc of movement of each mold While such 16 mold is being filled.
